CAREER: Particle Finite Element Response Sensitivity Analysis of Fluid-Structure Interaction

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该教师早期职业发展（CAREER）项目的研究目标是开发用于流体-结构相互作用数值模拟的分析灵敏度方法。 灵敏度法可用于海岸结构物的设计和评估。 在基于性能的工程的可靠性和优化应用中也需要它。 研究方法是基于直接微分方程的粒子有限元法，其次是数值验证和实验验证的海啸波盆地在O.H.俄勒冈州州立大学欣斯代尔波浪研究实验室。 内容包括流体-结构相互作用对不确定流体和结构参数的敏感性的建模、分析和可视化工具;流体-结构相互作用敏感性的高性能计算方法;研究成果的出版，以便更广泛地传播给其他研究人员和从业人员;和文件的方法，供他人应用。这项研究的结果，如果成功，将进一步深入了解沿海结构如何应对海啸和飓风风暴潮产生的荷载，可能会导致改进设计规范。 在开源软件框架OpenSees中开发建模和分析工具，将使该项目的结果随时可供其他参与流体-结构相互作用研究的研究人员使用。 研究生将受益于这个项目的课堂教学的方式在流体-结构相互作用的敏感性和积极参与研究。 该项目将使本科工程专业的学生在学术生涯的早期接触计算和可视化，并将开发跨学科的高级顶点课程，以使土木工程专业的学生在专业实践中认识到软件工程。 该项目的外联和大使部分旨在吸引对计算机感兴趣的高中学生攻读土木工程学位。

This award is funded under the American recovery and Reinvestment Act of 2009 (Public Law 111-5)The research objective of this Faculty Early Career Development (CAREER) project is to develop analytic sensitivity methods for numerical simulations of fluid-structure interaction. The sensitivity methods can be employed in the design and assessment of coastal structures. It is also need in reliability and optimization applications for performance-based engineering. The research approach is based on direct differentiation of the equations that govern the particle finite element method, followed by numerical verification and experimental validation at the tsunami wave basin in the O.H. Hinsdale Wave Research Laboratory at Oregon State University. Deliverables include modeling, analysis, and visualization tools for the sensitivity of fluid-structure interaction to uncertain fluid and structural parameters; high performance computing methods for fluid-structure interaction sensitivity; publication of research results for wider dissemination to other researchers and practitioners; and documentation of the approach for application by others.The results of this research, if successful, will provide further insight in to how coastal structures respond to loads generated by tsunami runup and hurricane storm surge, potentially leading to improved design codes. The development of modeling and analysis tools in the open source software framework, OpenSees, will make the results of this project readily available to other researchers involved in fluid-structure interaction studies. Graduate students will benefit from this project by way of classroom instruction in fluid-structure interaction sensitivity and active participation in the research. The project will expose undergraduate engineering students to computing and visualization early in their academic career and an interdisciplinary senior capstone course will be developed in order to make civil engineering students cognizant of software engineering in professional practice. The outreach and ambassador components of the project aim to attract high school students interested in computing to pursue a degree in civil engineering.
